I can use only one which I found a pain in ........ because my cat grabs them with her teeth and runs away. therefore I have to carry my pincushion every step I make, from my sewing machine to my ironing board and to my cutting table. when I'm through with sewing I have to hide it in my sewing machine cabinet, I have to cover my metal sewing accessories/tool and pick up everything from my cutting table. But she's so adorable that I give in to her bad habits. Cats really rule your life and cat lovers just love it
